摘　　要：针对小区域大高差似大地水准面拟合,利用空间定位技术提供的高精度三维坐标离散数据,对二次曲面、三次曲面、移动曲面和多面函数等多种模型进行拟合分析,使用VB编程技术开发曲面拟合程序,结合某矿山实例对不同函数模型的拟合效果进行验证,得出二次曲面、移动曲面和正双曲面这三种模型适用于不规则曲面的拟合,程序运行稳定,可为工程技术人员提供源代码支持。Aiming at the fitting of quasi-geoid with large elevation difference in small area,the highprecision three-dimensional coordinate discrete data provided by space positioning technology are used to fit and analyze the quadric surface,cubic surface,moving surface and multi-function models. The surface fitting program is developed with VB programming technology. The fitting effect of the models is verified in a mine,and it is concluded that quadric surface,moving surface and hyperboloid are suitable for irregular surface fitting. The program runs stably and can provide source code support for engineers and technicians.
